Operating Basics
Ensure the center of the fingerprint is on the sensor when swiping the
finger.
The following illustrations show the correct way to slide your finger over the
recognition sensor.
Align the finger and sensor like the drawings.
Points to note about the Fingerprint Sensor
Please be aware of the following considerations when using the fingerprint
sensor. A failure to follow these guidelines might result in damage to the
sensor, sensor failure, fingerprint recognition problems or a lower
fingerprint recognition success rate.
■ Do not scratch or poke the sensor with your nails or any hard or sharp
objects.
■ Do not press the sensor strongly.
■ Do not touch the sensor with a wet finger or any wet objects - keep
sensor surface dry and free of water vapor.
■ Do not touch the sensor with a soiled or dirty finger as minute foreign
particles of dust and dirt may scratch it.
■ Do not paste stickers or write on the sensor.
■ Do not touch the sensor with a finger or any other object which may
have a built-up of up static electricity on it.
■ Avoid swiping with the finger stiff or pressed-on too hard
Fingerprint reading may fail if the center of the fingerprint is not
touching the sensor, or when the finger is swiped while pressing hard.
Make sure that the center of the fingerprint is touching the sensor
before swiping.
■ Confirm the center of the fingerprint whirl before swiping
The thumb's fingerprint has a bigger whirl, which is prone to
misalignment and distortions. This will cause difficulty in registration and
a drop in the authentication success rate. Always confirm the center of
the fingerprint whirl so that it is swiped along the centerline of the sensor.
■ When fingerprint reading is not successful
There is a possibility of authentication failures if the finger is swiped too
quickly or too slowly. Follow the onscreen instructions to adjust the
speed of the swipe.
